Usually, the value of N can be proportional to the length of the first picture, and the longer the first picture is. , the value of N can be larger accordingly, the length of the first picture is smaller, the value of N can be smaller accordingly.

Step 302: Translate each line in the first image according to the grayscale image to obtain a second image, where the second image includes the outline of the image in the first picture.

The image included in the second image is composed of lines, and the image included in the second image is more abstract than the image included in the first picture. The first image includes an image coordinate system, and the position of a pixel on each line in the first image may be the coordinate of the pixel in the image coordinate system.

This step can be implemented through the following operations from 3021 to 3022, respectively:

3021: Transform each line in the first image into a curved line to obtain a third image.

For any line in the first image, for the convenience of description, the line is called the first line, and according to the position of the pixel included in the first line, the random value of the pixel included in the first line is obtained through a random function; A random value of the pixels included in a line and the interval between the first line and the second line, obtaining the first offset value of the pixels included in the first line, and the second line is an adjacent line of the first line; According to the first offset value of the pixel points included in the first line, the pixel points included in the first line are respectively translated to obtain a curved line.

Optionally, the pixels included in the first line may be translated along the direction of one coordinate axis in the image coordinate system of the first image.

Optionally, the random function may be a Perlin noise function, a trigonometric function, a Perlin noise function, or the like. For any pixel on the first line, the position of the pixel in the first image can be obtained, and the position can be the coordinates of the pixel (x1, y1), and the coordinates of the pixel (x1, y1) Input any random function among Perlin noise function, trigonometric function and Perlin noise function, so that the random function generates a random value p according to the coordinates (x1, y1), according to the random value P and the first line and the second line The interval d between, obtains the first offset value of the pixel point p*d, * is the multiplication operation; according to the first offset value p*d of the pixel point, along the image coordinate system of the first image Translate the pixel point in the direction of the ordinate axis, and the coordinates of the pixel point after translation are (x1, y1+p*d); or, according to the first offset value p*d of the pixel point, along the first image The pixel point is translated in the direction of the abscissa axis in the image coordinate system, and the coordinates of the pixel point after translation are (x1+p*d, y1).

Since the position of each pixel included in the first line is input into the random function, the random value of each pixel generated by the random function may be different, and the first offset value of each pixel obtained in this way is also different. When the first offset value of each pixel is parallel to each pixel on the first line, the first line is translated into a curved line. For example, after translating the lines in the first image shown in Figure 3-2, the effect diagram shown in Figure 3-3 is obtained.

3022: Translate the pixels included in each line in the third image according to the grayscale image to obtain a second image.

Wherein, since the size of the first picture is equal to the size of the first image, the size of the grayscale image of the first picture is also equal to the size of the third image.

Optionally, for any line in the third image, for the convenience of description, the line is called the third line, and the pixels included in the third line are obtained from the grayscale image according to the positions of the pixels included in the third line. The gray value of the point, according to the gray value of the pixel included in the third line, obtain the second offset value of the pixel included in the third line; according to the second offset value of the pixel included in the third line, respectively Translate the pixels included in the third line. The second image is obtained by translating each line in the third image as described above.

Optionally, the position of the pixel included in the third line may be the coordinates of the pixel in the image coordinate system of the third image. Assuming that the coordinates of the pixel are (x2, y2), it is obtained from the grayscale image. The gray value at the position of coordinates (x2, y2) is determined as the gray value of the pixel.

Optionally, the pixels included in the third line may be translated along the direction of one coordinate axis in the image coordinate system of the third image.

Optionally, there are multiple implementations for obtaining the second offset value of the pixel according to the grayscale value of the pixel. Only the following two implementations are listed in the embodiments of the present application, and other implementations are No more enumerating.

In the first implementation manner, the gray value of the pixel includes the gray value of the R channel, the gray value of the G channel and the gray value of the B channel. According to the gray value of the R channel, the gray value of the G channel and the gray value of the B channel of the pixel The gray value of the channel, and the second offset value of the pixel is obtained according to the following first formula.

The first formula is:

In the first formula, F is the second offset value, H _R , H _G , and H _B are the gray value of the R channel, the gray value of the G channel, and the gray value of the B channel, respectively, z ₁ , z ₂ , z ₃ and z ₄ are preset coefficients, for example, z ₁ , z ₂ , z ₃ and z ₄ may be 3, 6, 1 and 8, respectively.

In the second implementation, according to the coordinates (x2, y2) of the pixel, determine the first gray value of the first pixel at coordinates (x2, y2) in the grayscale image, and obtain the same value from the grayscale image. The second grayscale value of each second pixel point adjacent to the first pixel point, calculate the difference between the first grayscale value and each second grayscale value, calculate the average value according to the calculated difference values, and set the The average value is determined as the second offset value of the pixel point.

Assuming that the coordinates of the pixel point are (x2, y2), the second offset value of the pixel point is F, and according to the second offset value F of the pixel point, along the ordinate in the image coordinate system of the third image Translate the pixel point in the direction of the axis, and the coordinates of the pixel point after translation are (x2, y2+F); or, according to the second offset value F of the pixel point, along the horizontal direction in the image coordinate system of the third image. The direction of the coordinate axis translates the pixel point, and the coordinates of the pixel point after translation are (x2+F, y2).

It should be noted that: since the grayscale image includes the image information in the first picture, the second image is obtained by translating the pixels included in each line in the third image according to the grayscale image, and the obtained first The second image includes an outline of the image in the first picture. For example, if the first image includes a bird image, the second image obtained by translating the lines in the image shown in Figure 3-3 includes the outline of the bird image, as shown in Figure 3-4. Figure, in the rendering of the second image shown in Figure 3-4, the bird image is composed of lines.

Step 303: Set the pixel value of each pixel included in each line in the second image to obtain a second picture.

The first picture may be a color picture or a non-color picture. When the first picture is a color picture, the pixel value of each pixel included in each line can be set according to the first picture; when the first picture is an achromatic picture, the pixel value of each pixel included in each line can be set as a preset value. Set the ambient color pixel value.

For the operation of setting the pixel value of each pixel point included in each line according to the first picture, the operation adopts the Gaussian blurring method to process the pixel point of the first picture, and obtains the pixel value of each pixel point included in each line, so as to make The resulting second picture is more abstract and more artistic than the first picture. The implementation may include the following steps 3021 to 3023, respectively:

3021: According to the target position of the target pixel, obtain the target image area from the first picture, the target pixel is a pixel included in any line in the second image, and the position of the center pixel of the target image area is the target position , the radius of the target image area is the first radius threshold.

The target position may be the coordinates of the target pixel in the image coordinate system of the second image.

Optionally, find the pixel at the target position in the first picture as the center pixel, take the center pixel as the center, take the first radius threshold as the radius, and obtain an image area in the first picture as the target image area.

3022: Calculate the target pixel value according to the pixel value of each pixel in the target image area.

The pixel value of the pixel point includes the pixel value of the R channel, the pixel value of the G channel and the pixel value of the B channel.

In this step, for each pixel in the target image area, calculate the first average value of the pixel value of the R channel, the pixel value of the G channel and the pixel value of the B channel, and calculate the pixel value in the target image area according to the above method. The first average of each pixel of . According to the position of each pixel in the target image area and the target position, calculate the distance between each pixel and the target pixel, and obtain the corresponding pixel value according to the distance between each pixel and the target pixel. Weight value, multiply the first average value of each pixel point with the weight value of each pixel point to obtain the first value of each pixel point, calculate the second average value according to the first value of each pixel point, and set The second average determines the target pixel value.

Optionally, the correspondence between the distance range and the weight value can be saved in advance, so that for each pixel point, the distance range in which the distance between the pixel point and the target pixel point is located is determined. The corresponding weight value is obtained from the corresponding relationship of the values, and the weight value is determined as the weight value of the pixel point.

3023: Set the pixel value of the target pixel to the target pixel value.

The above steps 3021 to 3023 are repeatedly performed, and the pixel value of each pixel included in each line in the second image is set to obtain the second picture.

For example, when it is morning, the line color in the second image can be set to golden yellow, when it is noon, the second picture can be set to white, and when it is night, the second picture can be set to blue. Or, if the current environment is a snow environment, you can set the second image to white, the current environment is a desert environment, you can set the second image to khaki, and the current environment is a grassland environment, you can set the second image to grass green, The current environment is the sea environment, and the second picture can be set to sea blue.

In this step, when the execution subject of this embodiment of the present application is a terminal, for the type of geographical environment, the terminal can locate the current location, and find out the type of environment in which the current location is located from the server according to the current location.

For temperature information, the temperature value range corresponding to high temperature, the temperature value range corresponding to low temperature, the temperature value range corresponding to warm and the temperature value range corresponding to cold are defined in advance, so that the current temperature value can be obtained when the temperature information is obtained, and the current temperature value can be determined. The temperature value range in which it is located, and the temperature information corresponding to the temperature value range is obtained. Wherein, the current temperature value of its current location can be queried from the network, or, when the terminal includes a temperature measuring sensor, the current temperature value can be measured through the temperature measuring sensor.

The server can obtain the current time and obtain time information based on the current time.

3122: According to the environmental factor information of the current environment, obtain the environmental color pixel value corresponding to the current environment from the correspondence between the environmental factor information and the environmental color pixel value.

For any record in the correspondence between the environmental factor information and the environmental color pixel value, the record includes the environmental color pixel value and the environmental factor information corresponding to the environmental color pixel value, and the environmental factor information corresponding to the environmental color pixel value. At least one of geographic environment type, temperature information, and time information may be included. That is to say, the environmental factor information corresponding to the ambient color pixel value may be geographic environment type, temperature information or time information, or the environmental factor information corresponding to the ambient color pixel value may include geographic environment type and temperature information, or include The temperature information and time information either include geographic environment type and time information, or include geographic environment type, temperature information and time information.

3123: Set the pixel value of each pixel included in each line in the second image as the pixel value of the environment color corresponding to the current environment, to obtain a second picture.

For example, for the pixels included in the lines in the picture shown in Figure 3-4, after setting the pixel values of the pixels in the above two ways, the display effect of the second picture shown in Figure 3-5 is obtained.

Optionally, if the execution body of this embodiment of the present application is a terminal, the terminal may display the second picture according to the embodiment shown in Figure 4-1 below; if the execution body of this embodiment of the present application is a server, the server may send a message to the terminal. The second picture, so that the terminal can display the second picture according to the embodiment shown in Figure 4-1 below.

Optionally, when the terminal needs to display a picture, it can obtain the second picture according to the above steps 301 to 303, so that the terminal can display a different picture each time; Different pictures are displayed in each cycle.

In this embodiment of the present application, a grayscale image and a first image corresponding to the first picture are obtained, and each line in the first image is translated according to the grayscale image to obtain a second image, where the second image includes the first picture The outline of the image in the second image is set by setting the pixel value of each pixel included in each line in the second image in the second image to obtain the second picture. The second picture obtained in this way can be used for display after the terminal enters the extinguishing mode. Since the second picture is generated based on the original first picture after entering the extinguishing mode, different images for displaying in the extinguishing mode can be obtained on different terminals. pictures, to avoid the monotony and too single problem caused by the current display of preset pictures.

Referring to FIG. 4-1, an embodiment of the present application provides a method for displaying a picture, and the picture may be the second picture obtained by the embodiment shown in FIG. 3-1. The method can be used in the system shown in FIG. 1, and the execution subject can be a terminal, including:

Step 401: Display the second picture on the terminal screen; or superimpose a gradient mask on the second picture to obtain a third picture, and display the third picture on the terminal screen.

The second picture may be obtained by the terminal through the embodiment shown in Figure 3-1 above; or, the second picture may be sent by the terminal receiving the server, and the server sends the second picture after obtaining the second picture through the embodiment shown in Figure 3-1. The terminal sends the second picture.

Optionally, after the terminal enters the off mode, the second picture may be displayed on the terminal screen; or, a gradient mask is superimposed on the second picture to obtain the third picture, and the third picture is displayed on the terminal screen. During implementation, the second picture can be displayed in the following situations:

In the first case, when the terminal just enters the off mode, the second picture is displayed on the screen of the terminal. Alternatively, a gradient mask is superimposed on the second picture to obtain a third picture, and the third picture is displayed on the terminal screen.

Optionally, when the terminal just enters the off mode, the duration of displaying the second picture or the third picture on the screen of the terminal may be equal to the preset duration threshold.

In the second case, after the terminal enters the off mode and it is detected that the terminal is operated by the user, a second picture is displayed on the screen of the terminal. Alternatively, a gradient mask is superimposed on the second picture to obtain a third picture, and the third picture is displayed on the terminal screen.

Usually, when a user picks up the terminal to watch the terminal screen or operate the terminal, the terminal shakes accordingly. For example, the user picks up the terminal from a bag he carries with him to watch the screen of the terminal, or the user picks up the terminal from his clothes pocket to watch the screen of the terminal. At this time, the terminal can detect the occurrence of shaking, and then determine that the terminal is operated by the user. Since the user watches the terminal screen when operating the terminal, the second picture or the third picture can be displayed for the user to watch.

Optionally, the terminal includes at least one motion sensor among a gyroscope, a gravity sensor, an acceleration sensor, etc., and the motion parameter of the terminal is collected by the motion sensor, and when the motion parameter exceeds a preset parameter threshold, it is determined that the terminal shakes.

In the third case, after the terminal enters the off mode and it is detected that the distance between the obstacle in front of the terminal screen and the terminal screen is smaller than the first distance threshold, the second picture is displayed on the terminal screen. Alternatively, a gradient mask is superimposed on the second picture to obtain a third picture, and the third picture is displayed on the terminal screen.

In the third case, the terminal can be a terminal device such as a TV set or a monitor. The terminal is often fixed in a certain position. Usually, the user will walk towards the terminal. When the user approaches the terminal, the distance between the user and the terminal screen is When the distance is less than the first distance threshold, the second picture or the third picture is displayed, so that the user can view the displayed second picture or the third picture.

Optionally, the terminal may include a distance sensor or a proximity sensor, and the distance sensor or the proximity sensor can detect whether there is an obstacle in front of the screen of the terminal and the distance between the obstacle and the screen of the terminal.

Optionally, the gradient mask includes a display area and a non-display area, the transparency of the non-display area is less than or equal to a transparency threshold, the center position of the display area is a preset position of the terminal screen, the radius of the display area is the second radius threshold, and the display area is Regions that are farther from the center have less transparency.

The transparency threshold can be a lower transparency value such as 0, 1%, or 2%, so that the fourth slice below the non-display area cannot be displayed.

When the display area is a regular graphic area, the center position of the display area is the geometric center position of the display area. For example, when the display area is a perfect circular area, the center position of the display area is the geometric center position of the display area. When the display area is an irregular graphics area, the center position of the display area is the center of gravity of the display area.

The preset position of the terminal screen is a pre-defined position, for example, the preset position may be a position directly below the center position of the terminal screen and the distance from the center position is a preset value, or it may be directly above the center position of the terminal screen and away from the center The distance of the position is the position of the preset value. Assuming that the preset value is 200 pixels, the preset position is directly below the center of the terminal screen and 200 pixels away from the center, or the preset position is directly above the center of the terminal screen and 200 pixels away from the center.

In this step, a gradient mask can be superimposed on the second image through the following steps 4021 to 4022, which can be:

4021: Superimpose a layer of mask on the second picture, wherein the transparency of the mask is less than or equal to the transparency threshold.

Since the transparency of the mask is small, which is less than or equal to the transparency threshold, the mask can block the display of the second picture.

Optionally, the color of the mask can be black. The mask can be a layer.

4022 : Set a display area on the mask to form a gradient mask to obtain a third picture, and other areas of the gradient mask except the display area are non-display areas.

First, the preset position of the terminal screen can be determined. For example, the position directly below the center position of the terminal screen and the distance from the center position is the preset value can be found and used as the preset position, or the position directly below the center position of the terminal screen can be found. The distance above and from the center position is the position of the preset value and is used as the preset position.

Then, a circular area is determined in the mask with the preset position as the center and the second radius threshold as the radius as the display area.

Wherein, the second radius threshold includes a first radius and a second radius, the first radius is greater than the second radius or the first radius is less than the second radius; if the current terminal screen is placed in the vertical screen, the preset position in the mask is set as The center of the circle and the first radius are used to determine a circular area as the display area; if the current terminal screen is placed horizontally, the preset position in the mask is used as the center and the second radius is used to determine a circular area as the display area.

Finally, set the transparency of areas farther from the center in the display area to be less. The transparency of the center position of the display area may be 100%, and the transparency of the edge of the display area may be a preset transparency threshold.

In this step, by superimposing a gradient mask on the second picture, for example, adding a gradient mask to the picture shown in Figure 3-5, the resulting image of the third picture is shown in Figure 4-2, adding a gradient The mask can realize gradient display, which can improve the display effect and increase the user experience.

In order to improve the display effect and increase the user experience, when the user's finger touches the screen of the terminal, the brightness of the second picture or the third picture can be adjusted and/or the area of the display area of the gradient mask can be adjusted. The details are as follows:

Step 402: Acquire a touch parameter of the touch terminal screen, where the touch parameter includes at least one of a touch point position, a touch area, and a pressure for pressing the terminal screen.

The terminal screen may be a touch screen. When a user's finger touches the terminal screen, a touch event generated by the touch screen can be detected, and the touched touch area of the terminal screen and/or the pressure pressing the terminal screen can be obtained. The touch point position can be the center position of the touch area

Step 403: According to the touch parameter, perform an operation for adjusting the display effect of the second picture or the third picture.

The operation of adjusting the display effect of the second picture may include translating the pixels included in the lines in the second picture, and adjusting the brightness of the pixels included in the lines in the second picture; the operation of adjusting the display effect of the third picture may include translating the third picture.

Optionally, in this step, the pixels in the second picture or the third picture can be moved in a direction away from the position of the touch point, and the implementation process can be as follows:

For any first pixel, if the first pixel is located above the touch point, the first pixel is shifted upward according to the third offset value of the first pixel. If the first pixel is Below the touch point, the first pixel is shifted downward according to the third offset value of the first pixel. And, for any second pixel point, if the second pixel point is located above the touch point position, then according to the fourth offset value of the second pixel point, translate the second pixel point upward, if the second pixel point If the pixel point is located below the position of the touch point, the first pixel point is shifted downward according to the third offset value of the first pixel point.

Optionally, in this step, the pixels in the second picture or the third picture can be translated in a direction close to the position of the touch point, and the implementation process can be as follows:

If the point is located below the position of the touch point, the first pixel point is translated upward according to the third offset value of the first pixel point. And, for any second pixel point, if the second pixel point is located above the touch point position, then according to the fourth offset value of the second pixel point, move the second pixel point downward, if the second pixel point If two pixels are located below the position of the touch point, the first pixel is shifted upward according to the third offset value of the first pixel.
